Clinique iD Dramatically Different For Uneven Skin Tone

This product contains good ingredients to attract water to the upper layer of the skin. These ingredients are called "humectants": glycerin, hydroxyethyl urea.

When humectants are on the surface of the skin, they “pull in” the moisture from the outside environment, or from within deeper layers of the skin. If the air is dry, humectants can speed up the moisture loss from the skin. This is why it is a good idea to use another product on top of this one to help "seal in" the moisture (look for ingredients like dimethicone, squalane, oils and butters).

This product can help exfoliate the skin. In other words, it helps break down the bonds between dead cells on the surface of the skin and speed up the skin turnover. Skin often appears softer and brighter after exfoliation, but overdoing it can result in disrupted skin barrier. The following ingredient is doing the exfoliating job in this product: hydroxyethyl urea.

This product might help improve the skin tone through exfoliation. In other words, it helps to speed up the shedding of cells from the upper layer of the skin, and this might help reduce hyperpigmentation.

This product contains antioxidants (caffeine, scutellaria baicalensis root extract, taurine). In theory, they could help neutralize free radicals in skin and lessen the damage it gets from the UV light (sun), but there is no evidence that these ingredients can have a noticeable effect in skin.
